OPERATION CS-355T Handling Fuel Fuel is VERY flammable. Use extreme care when mixing, storing or handling, or serious personal injury may result. • Use an approved fuel container. • DO NOT smoke near fuel. • DO NOT allow flames or sparks near fuel. • Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize. • NEVER refuel a unit when the engine is HOT or RUNNING! • DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
CS-355T OPERATION Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use. Chain Lubricant Note: Cap indication - Fuel/oil tanks are indicated by the following illustrations Proper lubrication of the chain while in operation reduces friction between the chain and the guide bar to a minimum and assures a longer service life. • Use bar and chain oil of high quality for this purpose. • Do not use used or reclaimed oil to avoid various oiler problems.

B Checking Chain Tension Chain tension should be checked frequently during work and corrected as necessary. Do not operate with a loose chain.
CS-355T OPERATION • Do not let the tip of the bar touch anything while the engine is running. At cutting speed the chain is moving at a high rate of speed. Should the tip contact a limb or log while the chain is moving, the tip will be pushed upward with considerable force. This is known as kickback. Avoid it! In all circumstances the operation of the chain saw is a one-man job. It is difficult at times to take care for your own safety, so don’t assume the responsibility for a helper as well.
OPERATION CS-355T Felling the Tree A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power line, or another tree. There are ways to make a tree fall where you want it, so first decide where that is! For more information on scan this QR code. 3 m (10 feet) Direction of fall Before cutting, clear the area around the tree. You will need good footing while working and you should be able to work the saw without hitting any obstacles. Next, select a path of retreat.
CS-355T OPERATION Don’t cut with the saw overhead or aligned vertically with your body. If the saw should kickback, you may not have enough control to prevent possible injury. Bucking Bucking is the sawing of a log or fallen tree into smaller pieces. There are a few basic rules which apply to all bucking operations. Uphill position • Keep both hands on the handles at all times. • Support logs if possible. • When cutting on a slope or hillside, always stand uphill.
